In theory, that could happen, but the chances are very small. Most importantly, your investments would remain safe. They are separate from UpToMore B.V. and are held in a separate entity: UpToMore Fund N.V.
That entity exists only to hold your investments and is not allowed to do anything else with them. Every day, an independent party — the “depositary” — checks whether the money you invest through UpToMore is safely held in the name of UpToMore Fund N.V. If there is even the slightest doubt, the depositary reports this to the AFM, the Dutch Authority for the Financial Markets. UpToMore’s depositary is BNP Paribas, which can be found in the AFM register.
Only in the case of fraud could it happen that money is not held in the name of the foundation. For this unlikely situation, there is an additional safety net: the investor compensation scheme, up to €20,000 per person.
